c6 HELP!!

I have a 1994 ford f250, I just rebuilt the 351 engine. I also rebuilt the c6 tranny. Everything worked great for 2 days but now the tranny slips and I cant always get it into drive unless I rev it a little. Also the tranny clunks or sounds like something’s in it when I rev the engine in neutral. ANYONE HAVE ANY IDEAS (could it be the torque converter I put it on wrong the first time and had it binding to where the engine wouldn’t even turn over.)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
<o></o>
Thanks<o></o>

aaaaaaaaaaaaaaaaaayup.

If you put that much crush on the transmission it could damage the drive gear, stator support or both.

If the filter were that clogged it would not move anywhere.
It could have taken that long for the damage to show itself.

Drop the pan and have a look at any contamination.

What kind of filter did you put in it?

Please don't say dacron!

If you tweaked the tc, you could have caused a crack or bend that would become worse while running. More force applied makes it worse every time it is loaded. Pull it apart before it comes apart.

I have to assume you mean you can put it into drive, but, it does not go anywhere unless you rev the engine. To me that says damaged TQ or fluid leak/loss somewhere, in any vehicle.

I would drop the pan and look for metal.

You will probably find metal particles.

As for it being the convertor, not likely.
But if the pump is toast the convertor could follow suit.

Did you tighten the valve body bolts correctly?
Did you tighten the banana plate after the 2 halves were bolted together?
Did you install a gasket under the separator plate?
If so did you match the holes?
Once you get the pan and valve body off you can apply the various components using compressed air.

Focus on this part of the OP:

"..... (could it be the torque converter I put it on wrong the first time and had it binding to where the engine wouldn’t even turn over....."


TC bent? Damaged?

Pull it apart, it isn't going to heal up if you let it set for a few days.

Having to rev it to get it to engage sounds most likely that he missed the forward piston inner seal and/or the wear it causes.

But binding it that badly could have caused pump, converter, or other internal damage that could have taken a day or two to fail completely.

Like the USMC Drill instructor said.....STOP, GET BACK, DO IT AGAIN UNTIL YOU GET IT RIGHT!!!!!!!

Ex-wifes girl lent out her bowtie 4x to a friend and he brought it back at 2 mph ... Rebuilt the tranny 3 times before I figured out it was the converter ...
